Application filed. June 3, 1915. Serial No. 31,953.

To all whom it may concern:

Be it known that I, JACOB HENDRICKSON, a citizen of the United States,residing at Rossland, in the Province of British Columbia and Dominionof Canada, have invented a new and useful Permutation-Lock, of which thefollowing is a specification.

The present invention appertains to permutation locks, and aims toprovide a novel and improved lock of that nature adapted for use insafes, trunks, andthe like.

It is the object of the invention to provide a permutation lockembodying improved features of construction and operation, whereby anumber of successive operations are necessary to release thepartsheldtogether by the lock, to eliminate the possibility of any one without aknowledge of the combination opening the lock. 1

It is also within the scope of the invention to provide a permutationlock wherein a great many combinations may be had, that is, the devicebeing adjustable in order that the numerals of the combination may bechanged a largenumber of times.

With the foregoing and other objects in view which will appear as theydescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of whatis claimed without departing from the spirit of theinvention.

The invention is illustrated in the accompanving drawings, wherein 1Figure 1 is a front view of a safe, trunk, or other receptacleillustrating theexposed portions of the lock. Fig. 2 is an inside viewof the lock in locked position. Fig; 3 is a sectional view of the lock,taken on the line 33 of Fig. 4, with the parts in released or openposition. Figs. 4 and 5 are sectional views, taken on the lines 4:4E and55, respectivelv, of Fig. 2. a

In the drawings the numeral 1 designates a safe. trunk, or otherreceptacle having the hinged door 2 which carries the working journaledthrough the door 2., and having a dial disk a upon its outer end andresting against the outer side of the door 2. A spindle 5 is journaledthrough the tubular member 3 and has a dial disk 6 upon its outer endresting against the disk 4:. The disks 4 and 6 are suitably graduated.

A tumbler disk 7 is mounted upon the inner end portion of the spindle 5which projects beyond the inner end of the tubular member 3, andatumbler disk 8 is mounted upon the tubular member 3 adjacent the door 2or between the disk 7 and door. The tumbler disks are adapted to berotated upon the spindle 5 and tubular member 3 when the tumbler disksare released. The disks 7 and 8 are provided with marginal flanges 9 and10, respectively, projecting toward one another and providingcomplementing or adjacent recesses 11 and 12, respectively.

As a means for adjustably holding the disk 7' upon the spindle 5, an arm13 is slipped onto the inner end portion of the spindle5 and is soengaged to the spindle as to rotate therewith. through the arm or member13 and is arranged to threadedly engage one of an annular series ofthreaded apertures 15 provided in the disk 7 whereby the disk 7 may beset at a large number of angular positions relative to the spindle 5.

As a means for adjustablv holding the disk 8 upon the tubular member 3,a collar 16 is disposed non -rotatablv upon the tubular member 3 betweenthe disks 7 and 8. and a screw 17 is engaged through the collar 16. andis arranged to threadedly engage one of an annular series of threadedapertures 18 provided in the disk 8.

A screw 14 is engaged Theflange 9 of the disk 7 is provided with I placeupon said spindle and tubular member 3, a bar 21 is hinged at one end.as at 22, to an inwardly projecting supporting member 23 attached to thedoor 2. andthe bar 21 has an aperture 24 adjacent its free end 1 throughwhich the inner end of the spindle 5 is engageable when the bar 21 isswung into place. A cotter pin or other retaining" element 25 isengageable with the inner end of the spindle 5 for holding the bar 21 inplace upon the said spindle. The bar 21 thus holds the arm 13 in placeupon the spindle, and the arm 13 holds the disk 7 in place, while thedisk 7 holds the collar 16 upon the tubular member 3. The collar 16holds the disk 8 in place.

hen it is desired to change the combination, the cotter pin or retainingelement 25 is removed, in which event, the bar 21 may be swung away fromthe spindle 5, and this allows the arm 13 and disk 7 to be drawn 01? ofthe spindle 5. The screw 17 is thus uncovered and may be released fromthe disk 8, which allows the disk 8 to be adjusted relative to thecollar 16. After the disk 8 is adjusted properly, the screw 17 isreapplied to the disk 8 by threading the screw into the proper aperture18 of the disk 8. The disk 7 and arm 13 are then replaced, and byloosening or removing the screw 14, the disk 7 may be adjusted relativeto the arm 13 and spindle 5. so that the screw 14 in being reappliedwill hold the disk 7 in its new position with respect to the spindle.The bar 21 is then again swung into engagement with the spindle 5 forholding the parts thereon. and for also suppo t ng the spindle properly.

The receptacle 1 carries a finger or keeper 26 which projects toward thetumbler disks 7 and 8 when the door 2 is closed, and the finger 26 has ahead or knob 27 at its free end which is adapted to be received betweenthe tumbler disks within the flanges 9 and 10 thereof. The head 27 ismovable through the slot 19 when the tumbler disks are properlyarranged. Thus, when the tumbler disks are set so that the notches 19and 20 aline with the finger 26, the head 27 of the finger 26 can movethrough the slot 19 when the door is closed or o ened. When the head 27is disposed between the tumbler disks and the tumbler disks are disarranged, the head 27 will be locked within the flanges of the tumblerdisks to prevent the parts from separating.

A pair of spindles 28 and 29 are journaled through the door 2 adjacentthe tumbler disks. and have the respective knobs 30 and 31 secured upontheir outer ends. Arms 32 and 33 are secured upon the spindles 23 and29, respectively. upon the inner side of the door 2, and proiect toopposite sides of the tumbler disks. The arms 32 and 33 have theangularly extending fingers 34 and 35 at their free ends, respectively.which fingers project toward the tumbler disks. The said fingers 34 and35 have the heads 36 and 37, respectively, adapted to pass through theslots 19 and 20 of the tumbler disks and to be engaged by the flanges ofsaid disks. The fingers 34 the respective openings 38 and 39 provided inkeepers 40 and 41 carried by the recepand 35 are projectable throughtacle 1 at opposite sides of the finger 26. The fingers 34 and 35 arearranged to pass through the openings 38 and 39, respectively, when thefingers 34 and 35 are swung into engagement with the tumbler disks.

The arm 33 has a portion 42 projecting therefrom, and the free end ofthe portion 42 is engageable with the arm 32 after the arm 32 has beenswung into engagement with the tumbler disks, and when the arm 33 isswung into engagement with said disks, the arm 32 is held in engagementwith the tumbler disks until the arm 33 is released. 1 i I is lVhen thedoor is locked, there are three means for holding the door closed, andit equires a predetermined successive manipulation of a number of partsto liberate the door. lVhen the door is closed, the fingers 26, 34 and35 are projected or engaged between thetumbler disks. The fingers 26being held between the tumbler disks will prevent the door from beingopened, and the fingers 34 and 35 being engaged through the keepers 40and 41, respectively. and being disposed between the tumbler disks, willalso prevent the door from being opened. This provides three distinctmeans for holding the door closed, and it is necessary to release thearm 33, arm 32 and finger 26 in succession from the tumbler disks toopen the door.

To open the door, the arm 33 is first released from the tumbler disksand keeper 41, this being accomplished by first properly setting thedial disks 4 and 6 with respect to the pointer 43 provided upon the door2, so that the notches 19 and 20 of the tumbler disks register with thefinger 35 of said arm 33. The knob 31 is then turned in the properdirection to swing the arm 33 away from the tumbler disks, and this willretract the finger 35 from between the tumbler disks and out of thekeeper 41. At the same time, the projecting portions 42 of the arm 33 isswung out of engagement fromthe arm 32. Next, the dial disks 4 and 6 areproperly adjusted to bring the slots 19 and 20 into alinement with thefinger 34 of the arm 32, and the knob 30 is then swung properly to swingthe arm 32 away from the tumbler disks. This will retract the finger 34from between the tumbler disks and out of the keeper 40. Now, thetumbler disks are again set to bring the notches 19 and 20 intoalinement with the finger 26, and in which event, the finger 26 willmove through the slot 19 to allow the door 2 to be swung open. It thusrequires three adjustments of each of the two dial disks 4, or sixadjustments in all and a proper manipulation of the knobs 30 and 31 torelease the lock, and the arm 33, arm 32, and finger 26 must be releasedin succession from the tumbler disks. As a result, the lock cannot bereamaze leased without the combination being known, and'the lock willserve its office in a thoroughly eflicient and practical manner. Thecombination may be changed a large number of times, as above indicated,and to lock the door closed, the operation above described is reversed,as will be apparent without further description being necessary. Inother words, it is necessary to first engage the finger 26 with thetumbler disks, and then the arms 32 and 33 in succession.
